Sustainable fabrication of silver-titania nanocomposites using goji berry (Lycium barbarum L.) fruit extract and their photocatalytic and antibacterial applications |
| 초록 |
Silver-titania nanocomposites (Ag-TiO2 NCs) have unique functional attributes due to their photocatalytic and antibacterial properties. In this study, titania nanoparticles (TiO2-NPs) were successfully in situ decorated with silver nanoparticles (Ag-NPs) using the extract of goji berries (Lycium barbarum L.) as a reducing and stabilizing agent. Different Ag-TiO2 NCs were synthesized by treating different concentrations of silver nitrate (0.5, 1.0, and 1.5 mM) with a constant amount of TiO2-NPs in the presence of fruit extract. The average size of Ag-NPs on TiO2-NPs increased from 11.2 ± 3.05 nm to 16.4 ± 4.5 nm with an increase in the concentration of silver ions. These NCs exhibited excellent photocatalytic degradation of azo dyes, methylene blue (MB), and Congo red (CR). Ag-TiO2 NCS also exhibited good antibacterial activities towards Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative). |
